Product Description

When used on the side mounting surfaces of an M-Lok handguard, the Offset Picatinny Mount places the light at a 45 degree angle and tucks it in for a low profile. Oriented upwards, the light is located at approximately the 1:30 or 10:30 clock positions. Oriented downwards, the light is located at approximately the 4:30 or 6:30 clock positions.

The Offset Picatinny Mount also provides multiple side-to-side mounting positions and is reversible, which allows the user to move the light closer or farther away from the top rail, front sights, or other accessories. Six positions are provided, spanning approximately 0.50″.

The Offset Picattiny Mount is compatible with most M-Lok handguards like the Geissele SMR MK4, MK8, MK13, and MK14, Mega/Zev MML and Wedge Lock, Midwest Industries SSM, EraThr3, Stubborn Mule SMLock, Daniel Defense MFR, and SLR Rifleworks M-Lok models.

Arisaka Defense Offset Picatinny Mount -M-LOK

The quality of these (pieces) feels good, however the design is somewhat lacking. There is no need for this to be a 2 piece system. Plenty of other companies already make this in a solid one piece configuration which is what I thought this was.

Won’t be buying again.
